Database Backup
Database backup is the process of creating and storing copies of a database's data and structure to protect against data loss from hardware failures, human errors, cyberattacks, or disasters. It involves capturing a point-in-time snapshot of the database, which can be restored to recover data. This is a critical component of database administration and disaster recovery planning.
Developers should learn database backup to ensure data integrity and availability in production systems, especially for applications handling sensitive or critical information like financial records or user data. It's essential for compliance with regulations (e.g., GDPR, HIPAA), minimizing downtime during outages, and enabling safe testing environments by restoring from backups.
